Eiko non-dimmable 43W 4000K double-ended ballast bypass T8 glass LED lamps replace an 8' 59W T8 or 60/75W T12 fluorescent lamps. The double-ended feature requires the sockets on each end to be shunted so both pins are connected. Integrated driver for direct wire installation. Excellent color consistency and ideal for offices, schools, hospitals, hotels and other applications. Safe to use in fixtures where ambient temperature is between -4°F to 113°F.
Line Driven - Ballast must be bypassed when present.
- Integrated driver bypasses existing ballast
- NSF certified
- Perfect for applications with frequent "on/off" switching cycles, and buildings that desire to be mercury free
- Power must be turned off at the fixture before replacing the lamp
- Instant on, no flicker or buzz
- Emits virtually no UV rays or IR
- Suitable for damp locations
A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.
The total wattage of fluorescent lamps in a fixture that this fixture replaces.
A measure of "electrical pressure" between two points. The voltage specification of an incandescent lamp is the electrical "pressure" required to drive it at its designed point. The "voltage" of a ballast (e.g. 120 V) refers to the line voltage coming from the power source and is connected to the ballast.
The end (or ends) of the lamp that fits into the socket.
Wiring configuration a bulb can work with. Can be single-ended, double-ended or both.
The description of the general appearance of a lamp/bulb consists of a letter(s) followed by a number. The letter indicates the shape of the bulb and the number relates to the diameter of the bulb in eighths of an inch. For example, a common household bulb is the A-19. The bulb is "A" shape and the diameter would be nineteen 8ths of an inch, or 2 3/8".
The color of the light produced by a bulb
Color Rendering Index is an international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale) the richer and more accurately colors generally appear. CRI differences among lamps are not usually visible to the eye unless the difference is more than 3-5 points.
|Color Temperature (Kelvin)
Color Temperature (Kelvin)
An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).
A rating of the initial light output of a bulb, rated after 100 hrs of operation. Lumens are a measure of how much light falls on one square foot of area, one foot away from the light source.
The surface finish of a bulb, which may affect the quality of the light emitted.
The technology implemented by the bulb, e.g. incandescent, halogen, LED
|Average Rated Life (hr)
Average Rated Life (hr)
A measurement of the average length of time, between first use and the point when 50% of the lamps tested have stopped functioning, , using an operating cycle of 3 hours on, 20 minutes off.
|Operating Temperature (°F)
Operating Temperature (°F)
The ambient temperature in which the product can safely operate.
|-4 to 113
|Bulb Power Type
Bulb Power Type
Defines how a lamp is powered, whether it needs a ballast or not, or can use either
Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.
Light bulbs: a measurement of a bulb's width taken at the widest point of the bulb. Fixtures: the measurement across the widest point of a circular fixture.
Type of socket a linear lamp is compatible with, whether shunted, non-shunted or both.
